Internal combustion engines and the principles of their operation are well known. As a basic to all, a fuel mixture typically consisting of a combustible fuel such as gasoline or diesel is combined with a facilitating mixture of oxygen containing gas, most often air. It is possible that the air which is mixed with the combustible fuel be conditioned in one or more of several ways. Turbochargers are well known devices that can be added to combustion engines to potentiate their power development. Typically, a turbocharger will divert a portion of the exhaust gases from a running engine to be used for combining with the fuel source for injection into the piston cylinder(s). This achieves two benefits: the first is a pressuring of the fuel and gas mixture into the piston chamber and the second is a preheating of the mixture so that it is more readily ignited and thoroughly combusts. Because of the principles of the combustion engine, its efficiency is potentiated by those things that facilitate the input of fuel and air mixture, and also by those things that facilitate the removal of the spent exhaust products after ignition. For these reasons devices that can be incorporated into the original design of the piston-cylinder combination in an internal combustion engine will beneficially enhance the engine's performance. It is also possible that such facilitating features may be added subsequent to the original manufacture as retro-fit enhancements. The present invention has been developed to speak to these needs for enhancement and provide the same for an internal combustion engine.
